Question
The stability of dihalides of Si, Ge, Sn and Pb increases steadily in the sequence
-
GeX2 << SiX2 << SnX2<< PbX2
-
SiX2 << GeX2 << PbX2<< SnX2
-
SiX2 << GeX2 << SnX2<< PbX2
-
PbX2<< SnX2 << GeX2 << SiX2
Solution
C.
SiX2 << GeX2 << SnX2<< PbX2
Due to inert pair effect, the stability of +2 oxidation state increases as we move down this group.
